"Twilight" and Balenciaga might seem like an unusual pairing, but Kristen Stewart (who plays Bella in the series, for all of you non-Twihards), will be the face of the fashion house's next fragrance. "She shares the radical spirit of Balenciaga," says creative director Nicolas Ghesquiere. While details on the scent are still under wraps (it's scheduled to come out this fall), our guess is that it will be moody, mysterious, and maybe even a touch radical -- just like Stewart.
